library0.1.0jsnpmunverified

PostgreSQL driver for the Calypso query engine, providing a session-based API to query PostgreSQL databases using Calypso's DSL. Current stable version is 0.1.0. The package is in early development with no recent updates. It differentiates by integrating Calypso's query system with Postgres, but has very limited usage and documentation.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

PostgresDriver
✓ var PostgresDriver = require('calypso-postgres');
✗ var PostgresDriver = require('./driver');
The README shows requiring from a local path; the correct npm import is 'calypso-postgres'.
calypso
✓ var calypso = require('calypso');
Calypso is a separate package that must be installed.
Query
✓ var Query = calypso.Query;
✗ var Query = require('calypso').Query;
While functionally similar, exports may differ; best practice is to require calypso first.

Shows how to configure the Calypso engine with the Postgres driver, create a session, and run a query.

var calypso = require('calypso'); var Query = calypso.Query; var PostgresDriver = require('calypso-postgres'); var engine = calypso.configure({ driver: PostgresDriver.create({ uri: 'postgres://mdobs@localhost/mdobs' }) }); engine.build(function(err, connection) { if (err) throw err; var session = connection.createSession(); var query = Query.of('foobar'); session.find(query, function(err, objs) { if (err) throw err; console.log(objs); }); });
Debug
Known issues
deprecatedPackage has not been updated since 2013 and appears abandoned.
fix
Consider using other PostgreSQL ORM/query builders like Sequelize, Knex, or TypeORM.
affects: 0.1.0
gotchaThe Calypso ecosystem is very niche and the API may break between versions. Ensure calypso version compatibility.
fix
Lock calypso version to a known compatible one.
affects: 0.1.0
gotchaThe driver expects a Postgres URI; missing or incorrect URI leads to connection errors.
fix
Provide valid URI: 'postgres://user:password@host:port/database'.
affects: 0.1.0
